Description
The Barnes Harvest Collection brings together two names with serious hunting credentials. By pairing Barnes' loading expertise with Sierra's renowned Tipped GameKing bullet, you get ammunition that's purpose-built for taking larger game out to distance.
What Makes This Load Different
The Tipped GameKing bullet sits at the heart of this round. Sierra engineered this projectile with a transparent polymer tip seated in a hollow point design, giving you fast, consistent expansion on impact. The lead core wraps in a thick copper jacket that resists deformation, which means you get outstanding penetration alongside controlled expansion regardless of range. The boat tail profile keeps the ballistic coefficient high at .515, so your bullets maintain velocity and energy downrange where it counts. At 2960 fps from the muzzle, this load delivers 3501 foot-pounds of energy, making it suitable for any North American big game.
Built for Reloaders and Precision
Barnes loads these rounds with boxer-primed, reloadable brass that holds up through multiple reloads if you're into that side of things. Non-corrosive primers and consistent powder charges mean you get the same velocities and performance you expect from box to box. That kind of reliability matters when you're glassing a hillside waiting for the right opportunity.

Frequently Asked Questions
Is this ammunition suitable for reloading?
Yes. These rounds use boxer-primed brass cases that can be reloaded multiple times. The quality of the brass and consistency of Barnes' factory load specs make them a solid choice for reloaders looking to develop custom loads while maintaining the proven bullet performance.
What hunting situations is the .300 Win Mag 180gr best suited for?
This loading performs well on elk, moose, and other large game, especially when you're setting up for shots beyond typical hunting distances. The high ballistic coefficient keeps energy downrange, and the Sierra Tipped GameKing expands reliably at both close range and extended distances.
How does the Tipped GameKing bullet expand on impact?
The polymer tip initiates rapid expansion into the hollow point cavity, creating a large wound channel while the thick copper jacket penetrates deeply. This gives you the quick-kill characteristics hunters want while maintaining the bullet weight needed for proper penetration on bigger animals.
What makes Sierra Tipped GameKing bullets different from other hunting bullets?
Sierra spent over 70 years developing and refining their bullet designs. The Tipped GameKing combines Sierra's accuracy heritage with a hollow point hollow point design, boat tail profile, and polymer tip. The result is consistent expansion, minimal drift downrange, and the kind of terminal performance that's earned Sierra's reputation among serious hunters.
